Thank you for going through this and showing enthusiasm for it. As a student with learning disabilities, I find this patient approach much easier to follow than the professor's teaching style at my community college. God bless you, sir.

Why is the summation of f subtracted by 1 for the formula of variance

[@owilimildred3312]

When do you use this formula where the denominator is summation of f-1 and when do you use the other one where denominator is just summation of f?
